,iu claims. (01.14%11) a This invention relates toa power tak'e-ofi particularly adaptedior use on traveling machine shops and allied structures which are designed especiallytfor use by an army.

On these types of structures, there are numer- 'ous machine shop tools, such as drill presses, lathes; .milling machines. grinders, shapers, air compressors, welding machines and other apparatus necessary to make repairs in the field on aeroplanes, tanks, trucks, automobiles and, other Wtlj equipment and farm machinery. 'This imachinery equipment requires a rotary drive from the engine "which propels the vehicle. While power take-01f .devices have been heretofore -proposed and'used, mypresent inventionis directed to a simplification and improvement of priorart "structures.

Itis therefore them-incipal object of m invention tQrpIOVidG. arelatively simple and 'efiecjtive power take off from the vehicle engine to the machine tools carriedbythevehicle.

j Other ancillary objects willbe clear to one skilled in. this t pe of equipment. from areading of the following specification, taken in YCOHHBCF.

The sleeve 9 is "carried in a member 4 4 fastened to a bearing plate l 5 in any satisfactorywmanner as by screw-studs; lrfi. A packing H may be used as indicated. A ball bearing i8 carries one 1 end of thehousing'onthemember M. a i .A somewhat similarrconstructionisusedrat'the 1 driven end of the=housing. A'ballbearing ill is positioned between "the :housing and the i bearing member fastened to a support member-El by meansaof screw-studs 522. Positionedwithin the member 20, 'is-a driven sleeve 23 fastened to a drivenshaft 24 iby a key 25 and. 'nut "21s. The

innerracexbfthe bearing 19 is held to the mem- =ber":28 'by a'lockring 21; The inner end "of the sleeve 23 is preferably enlarged and terminates.

in a rim 28 'havinginternal gear teeth. 28 ,cut therein. Tothe inner peripheryof the housing is fastened a "hollow annular ring 30 havinggear teeth 3i alignment with the gear teeth 29 on the :sleeve 23. Positioned between theudrivingwsleeve 9 and the driven sleeve -23, is 312E831! combination comprisinga; gear 32 having a spaced disc-shaped member 33 integral therewith. A

gear 34'hasa stem 35 pr0jecting throughthedisc 33 and is-fastenedto thegear-and-disc structure in any satisfactory manner as by a pin 36. .By this-construction, whenever thegear 32 and disc. l

33 areshiftedythe gear 34 moveswiththem.

Theouter peripheral-surface of thedisc 33is Positioned within this annular groove are a pluralityof antifriction members in the form of rollers carried =on the inwardly projecting ends of .L;-shaped members 39 which are fastened as by screws 40;

to "a-hollow circular or cup-shaped member I4| that encompasses :the rim portion 1.2 of. the driving sleeve 9.

The member 41 hasta plurality of projecting armsALiourbeing indicatedin Figure .8. These arms extendthrough shallow slots in the outer surfacel of the memberlA. Oil'and dirt seals 5i within which driving. belt members :5 are-posi tioned. As shown in Figure 1'0, the outer annular flange 6 is separable from the housing and fas tened thereto by .a plurality of screws 1. As a matter of factQthe other flanges may be of the separable'type and fastened to the'parts of the casinglasitheseiparts are assembled.

Entering the casing afrom mneend, i 5 driving 53 are :used. at tbothends vof the casing; The .seal- 5: :atthe drivingend engages the arms 42, there.-

by preventing oil from the interior ofwthe casing escapingwia the arms asthe shifting operations are performed. To the arms .42 is iastened a shift lringlor collar 4-3,in.any satisfactorylnanner as by "screwestucls M. IIIhe shift .ring or collar flfhas a pair ofioppositely disposed studs: 45 pesitioned in holes or :slots in the endsnof -tupwardly extending arms 46 formed on the end of a lever 41 pivoted at 48 to a bracket 49 fastened engine, preferably by way of the transmission,

poweris conveyed to the housing and to the belt 1 drive 5 and through suitable interconnecting structures with the various machines. When,

the lever 41 is moved to the left; the member 4! shifts the gear combination' described, so that the gear 34 engages the gear teeth on the driven sleeve 23. Since this latter sleeve is connected to the driven shaft 24, power is' conveyed back to the differential of the vehicle and the, vehicle is driven according to the controls of the trans mission. I i

- When it is desired to-operate the machinery carried by the truck, the lever 41 is moved ,to the rightand the gears are shifted into the position shown in Figure 3 and asalready described. l Certain changes maybe made in the details without departing from the spirit of my invention or the scope of the appended claims; for example, in place of the member'4l havingprojecting arms 42, tubes may be passed through cooperating openings in the member [4, through which tubes fluid maybe passed to coact with hydraulic means associated with the member 4|.
